    Research Areas:

    Angelo Pio Rossi currently conducts research on comparative geology and geomorphology, including aeolian, fluvio-lacustrine and periglacial processes. He is also research associate with the HRSC (onboard ESA Mars Express spacecraft) and SHARAD (onboard NASA‚ Mars Reconnaissance Orbiter) experiments. He is interested in field geology of impact structures (e.g. West Africa). His experience includes Earth-based remote sensing data analysis for studying the geomorphology and paleohydrology of arid zones (e.g. Sahara).
